y ROOF COVERING Filed D90. 27, 1929 Patented Dec. 2, 1930 PATENT OFFICE HENRI GA'U'VIN,` 0F OTTAWA, ONTARIO, CANADA :aoor covnnme Application led December 27, 1929. Serial No. 416,895.

This invention relates to improvements in roof covering and the objects of the invention are to provide a roof covering which will simulate a thatched roof and yet avoid the i disadvantage attendant on this form of construction. Further objects are to provide a roof covering which may b e manufactured ready to lay at a relatively low cost, which may be laid in a simple manner` and which will form a water and weather proof covering possessing high heat insulating quality.

Further obj ects are generall to im rove and simplify the construction o a roo covering of this type better adapted in form to the function required of it. y

It consists essentially of an envelope of impregnated paper or other fibrous material containing a quantity of a projecting brush material held in the envelope with suitable cementitious material as hereinafter more fully set forth and described in the accompanying specification and drawings.

In the drawings, Figure 1 is a perspective vview of a portion of roof constructed with the roof covering made according to the present invention.

Figure 2 is a plan view of a portion of roof covering constructed according to the present invention with thel layers broken away to better illustrate the construction.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a perspective view of an alternative form of roof covering made in the form of a roll.

Figure 5 is a perspective viewof a special form of brush member which may beused 4in the roof covering.

In the drawings, like characters of reference indicate corresponding parts in all the figures.

The roof covering may be formed either as `separate shingles or as roll roofing. In Figures 1, 2 and 3 the shingle form is shown and in Figure 4 the roll form. InFi res 1 and 3, A indicatesI an envelope of suitable light, fibrous, weather-resisting material, such as paper obre board impregnated with water proofing material. Asbestos paper impreg- 50- nated with asphalt has been found to be a suitable material for the purpose. The envelope is'preferably closed on three sides, and.

a sultable quantity of brush material, B, is held within the envelope and projects outwardly therefrom. A variety of. material may be used as brush m'aterial, such as straw, reed, libre strand, metal strand or the like.

A very useful material is the brush or cane known as African bass. The brush material is held within the envelope with suitable ce- 60 mentitious material of a water proof character such as bitumen or asphaltum of a suitable consistency. The manner of constructing the shingle may be seen from Figure 2. In the broken away portion, 10 indicates the 65 bottom sheet of the envelope conveniently consisting of asbestos paper saturated with asphalt, 11 indicates a layer of bitumen or asphaltum placed on top of the paper, 12 indicates a brush material extending within the envelope, 13 a second la er of asphaltum or bitumen placed on top o the brush material, 14 represents the top sheet of asbestos paper saturated with asphalt. The brush material is adapted to project a suiiicient distance outwardly from the envelope to enable the brush material of successive shingles to overlap when laid as shown in Figure 1, to thereby produce the effect of a thatched roof. The edges of the envelope A may, if desired, 30 be bound with suitable binding strips, 15.

The roofing material may be constructed in roll form as shown in Figure 4 in which the envelope B1 is made continuous, the upper and lower surfaces being joined lonly at the outeredge. This material may be cut to length as desired and'laid in overla ping layers, similar to Figure 1. In both orms the bituminousfmaterial within the envelope is preferably applied hot, and the envelope is pressed firmly against the brush material in the process of manufacturing, to thereby thoroughly impregnate the brush material within the envelope and firmly hold it in position. The special form of brush material shown in Figure 5 comprisesla strand 16 of asbestos fibre or water proofed cotton and a spiral 17 of thin metal such as copper.' It is possible to obtain this material at comparatively low cost,- the copper being a, thin material held within turning wound around the string or cord forming the strand 16. When thls 1s applied to the roof, it soon weathers and acquires the well-known appearance of a copper roof.

As many changes could be made 1n the above construction and many apparently widely different embodiments of my invention within the scope of the claims constructed without departing from lthe spirit or scope thereof, it is intended that al1 matter contained in the accompanying specicatlon and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. As a new article of manufacture, a roof covering comprising an envelope, brush material held Within the envelope and projecting outwardly therefrom, and a cementitious material within the envelope about the brush material.

2. As a new article of manufacture, a roof covering comprising an envelope with impregnated paper, brush material therein, and a bituminous material within the envelope surrounding the brush material.

As a new article of manufacture, a roof covering comprising an envelope coated on the inside with a water proof cementitious material and a brush material held within the envelope, projectin therefrom.

4. As a new article o manufacture, a roof covering comprising asbestos paper impregnated with asphalt, brush material held within the envelope projecting therefrom and asphalting material within the envelope about the brush material.

5. As a new article of manufacture, an envelope member in the form of a roll, brush the envelope and projectingoutwardly therefrom and a cementitious material within th'e envelope surrounding the brush material.

As a new article of manufacture, a roof covering comprising an envelope, brush material within the envelope projecting outwardly therefrom and comprising a plurality of individual strands each surrounded with a copper spiral.

7. As a new article of manufacture, a roof covering comprising an envelope, brush material within the envelope projecting outwardly therefrom and comprising a plurality of individual strands each surrounded with a metal spiral.

In witness whereof my hand.

I have hereunto set HENRI GAUVIN.
